Sometimes a Timeout Error with send_video()

[joaomino]

Hi everyone, I’m having an issue with the send_video() function. Occasionally, it works, but most of the time, it throws a Timeout Error (see attached screenshot). It’s not a network issue on my end, as my connection is stable.

Any ideas on what could be causing this?

Here’s the code I’m using:

from atproto import Client, models
import os
import time


def main() -> None:
    client = Client()
    client.login(os.environ['BSKY_USERNAME'], os.environ['BSKY_PASSWORD'])

    # replace the path to your video file
    with open('./data/new_video.mp4', 'rb') as f:
        vid_data = f.read()

    root_post_ref = models.create_strong_ref(client.send_video(text='Video posted via send_video() without token', video=vid_data, video_alt='Video posted via send_video - test_game01.mp4'))

    vid_data=None

    time.sleep(60)

    # Reply to the root post. We need to pass ReplyRef with root and parent

        # replace the path to your video file
    with open('./data/test_game01.mp4', 'rb') as f:
        vid_data = f.read()


    reply_to_root = models.create_strong_ref(
        client.send_video(
            text='Reply to the root post via send_post()',
            video=vid_data,
            reply_to=models.AppBskyFeedPost.ReplyRef(parent=root_post_ref, root=root_post_ref),
        )
    )

main()

Could this issue be related to the audio codec?

I've tried posting the two videos separately. The version that works (test_game01.mp4) uses the AAC audio codec, while the one that throws the error (new_video.mp4) uses MPEG Audio layer 1/2 (mpga). After converting new_video.mp4 to AAC, the error disappeared. Both are using H264 for video.

I'll run a few more tests to confirm-

Not related.

I converted another video to H264/AAC, and it did not upload. Then I tried again the same video with the H264/mpga pair (new_video.mp4), and it uploaded successfully.

I updated my code to include a loop with 5 attempts in case the error occurs again.

Hi! Do you use your own PDS? If your connection is stable as you said, it is probably another client side issue. Do you use macOS? What values of your ulimit -a? Did you try to run it on the server?

upd. ah I see this is Windows

Hey! Thanks for getting back to me.

I’m not using a personal PDS; I’m testing this on a local Windows machine.

Hi, try to just increase timeout. There is not option in send_video for it, but you can use upload blob directly and pass own timeout!

Pseudo code (not ready to copy and paste):

client = Client()
client.login(......)

upload = client.com.atproto.repo.upload_blob(vid_data, timeout=60)
embed = models.AppBskyEmbedVideo.Main(video=upload.blob, alt='my video alt')
client.send_post('blabla my video', embed=embed)
